Protein

Tryptophan biosynthesis protein TrpCF

Gene

trpC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Bifunctional enzyme that catalyzes two sequential steps of tryptophan biosynthetic pathway. The first reaction is catalyzed by the isomerase, coded by the TrpF domain; the second reaction is catalyzed by the synthase, coded by the TrpC domain.

Catalytic activityi

N-(5-phospho-beta-D-ribosyl)anthranilate = 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate.
1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate = 1-C-(3-indolyl)-glycerol 3-phosphate + CO2 + H2O.

Pathwayi: L-tryptophan biosynthesis

This protein is involved in step 3 and 4 of the subpathway that synthesizes L-tryptophan from chorismate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Bifunctional protein TrpGD (trpGD), Anthranilate synthase component 1 (trpE)
  2. Bifunctional protein TrpGD (trpGD)
  3. Tryptophan biosynthesis protein TrpCF (trpC)
  4. Tryptophan biosynthesis protein TrpCF (trpC)
  5. Tryptophan synthase alpha chain (trpA), Tryptophan synthase beta chain (trpB)
This subpathway is part of the pathway L-tryptophan biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-tryptophan from chorismate, the pathway L-tryptophan biosynthesis and in Amino-acid biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
